There is in North-American Indian culture a much greater evaluation of silence than in English-speaking societies and in French-speaking societies as well. French philosopher Michel Foucault has also described that, "I think silence is one of those things that has unfortunately been dropped from our culture". Young Romans or young Greeks were taught to keep silent in very different ways according to the people with whom they were interacting. In the growing process of a person, choosing ways to develop silence in accordance with various situations is a cultural ethos to examine one's attitude and quality of life.
